im sure as long as you just get an answer; you will continue to type in the same kind of problem over and over again :)

assuming x is real: \[5 \sqrt((x+1)^2)+6 = 21\] otherwise: x+1=3

i don't know how to start it absolute value i just don't understand it

the absolute value is the last thing to work on; how do you get that absolute value all by itself?

5(x+1)+6=21 (5x+5)+6=21 5x+6=16 5x=10 x=2

looking at this question, what is the other solution for x if it was not an absolute value?

the term "absolute value" means that there is a quantifiable value; something that can be measured. length, height, area, volume, distance are all examples of abslute values

dont jus give him the answer he is probably usin this site for a summer school!!!

in other words; an absolute value doesnt care about what direction the sign takes us in; it only cares about a quantifiable measure

a is always positive, you discount the negative answer.

sky, you isolate the absolute value just like you would isolate a variable. Llort, no you do not 'discount' the negative answer. It is a valid solution.

12 has the same absolute value as 12

as a result; if we are determining any value for inside of the absolute value notation; we have to account for the positive and the negative results that occur within it

So if you have \[5x+1 + 6 = 21\] You want to isolate the term with the absolute value in it first. You do this by subtracting 6 from both sides of the equation.

What do you get when you subtract the 6?
 2 years ago

polpakBest ResponseYou've already chosen the best response.0
No, \(5x+1 + 6  6 = 21 6\) \[\implies 5x+1 + 0 = 15\]\[\implies 5x+1 = 15\]

polpakBest ResponseYou've already chosen the best response.0
So now lets say that x+1 is something, lets call it k.. So we have \(5k = 15 \)\[\implies \frac{1}{5}\cdot5k = \frac{1}{5}15\]\[\implies k = 3\] And since we said k was x+1 we have \[x+1 = 3\]So what values can x have and still make this equation true?

I am assuming the other answer is x=4
 2 years ago

polpakBest ResponseYou've already chosen the best response.0
x =4 is one solution yes, because 4 + 1  = 3 = 3
